Lepton polarization asymmetry in radiative dileptonic B-meson decays in MSSM

Abstract

In this paper we study the polarization asymmetries of the final state lepton in the radiative dileptonic decay of B meson (\bsllg) in the framework of Minimal Supersymmetric Standard Model (MSSM) and various other unified models within the framework of MSSM e.g. mSUGRA, SUGRA (where condition of universality of scalar masses is relaxed) etc. Lepton polarization, in addition of having a longitudinal component (\pl), can have two other components, \pt and \pn, lying in and perpendicular to the decay plane, which are proportional to \ml and hence are significant for final state being ${\mu }^{+}{\mu }^{-}$ or ${\tau }^{+}{\tilde{\tau }}^{-}$. We analyse the dependence of these polarization asymmetries on the parameters of the various models.
